Hello, you haven't provided the programing language in which you need the code, I'll explain how to do it using Python, and you can follow the same logic to make a program in the programing language that you need.
Answer:
1. # -*- coding: utf-8 -*-
2. #Python
3. class Calculator:
4. def add(self):
5. print(a + b)
6. def sub(self):
7. print(a - b)
8. def mul(self):
9. print(a * b)
10. def div(self):
11. print(a / b)
12.
13. obj = Calculator()
14. choice = 1
15. while choice != 0:
16. a = int(input("\nEnter first number: "))
17. b = int(input("Enter first number: "))
18.
19. print("\n0. EXIT")
20. print("1. DIVISION")
21. print("2. ADDITION")
22. print("3. SUBTRACTION")
23. print("4. MULTIPLICATION")
24.
25. choice = int(input("\nEnter your choice: "))
26. if choice == 1:
27. obj.div()
28. elif choice == 2:
29. obj.add()
30. elif choice == 3:
31. obj.sub()
32. elif choice == 4:
33. obj.mul()
34. else:
35. break
Explanation:
- From lines 1 to 12 we define the object with four methods, addition, subtraction, multiplication, and division. Each method contains the operation between two variables inside a print function
- On line 13 we instantiate our class
- On line 14 we declare the variable choice that is going to store the operation that the user wants to perform
- On line 15 we declare a while loop, this is going to keep running the program until the user wants to exit
- From line 16 to 18 we ask the user to enter two numbers
- From line 19 to 24 we print the possible operation, assigning a number for each operation, this indicates to the user what number to press for what operation
- On line 25 we ask the user for the operation
- From lines 26 to 35 we check the user input an accordingly we call the corresponding method to performs the operation
Answer:
The body of water that is most likely to be a marine ecosystem would be an estuary.
Explanation:
An estuary is a widened, often funnel-shaped mouth of a river, where fresh river water and salt sea water are mixed and thus brackish water is created, and where tidal differences can be observed. When a river flows as a system of branches, it is called a delta.
Estuaries often have a great natural value. They typically consist of swallows and salt marshes that are very rich in invertebrates and thus have a great attraction for birds, among other things.
Answer:
A geographic information system (GIS) uses spatial and nonspatial data and specialized techniques for storing coordinates of networks of lines (roads, rivers, streets) and reporting zones (zip codes, cities, counties, states).
Answer:
False.
Explanation:
The fixed program computer was used earlier which used wired processor and it was very laborious to make changes in processors. In the fixed program, the computer was following the build-in instructions and were processing only those data which were stored in memory.
Stored program computers are used in modern computers that are those computers that have single process structure and which will have instructions on how to perform the function on the computer and how to keep track of the processed data in computation.
Stored program computers keep program instruction in electronic memory.
Answer:
A. decide what is meaningful and useful and what is not
Explanation:
"Media" refers to the<u> different modes of communication </u>such as <em>TV, radio, Internet, newspaper, etc. </em>
"To Filter" means to<u> remove something that is not meant for people to know</u>.
So to speak, to filter the media means <em>to remove unnecessary information or useless information from the pool of information in the media.</em> This means that only the meaningful things or information will be relayed or posted for the audience/readers to know.
